All New HD 28185 Add-On Update with new pix and info!

[Don. Edwards]

Well boredom has its rewards. I pulled all my past work on the HD 28185 add-on and found it in a pretty sorry state. I had used it for testing many new textures and so it was not linking too many of the textures it was suppose to. I got that all fixed and finally got to go through and take a good look at how it stood.
I have just word. YUK! I can't believe I hoisted this thing off on everyone almost 2 years ago.
The textures by today’s standards are just plain bad. Well maybe not all of them but enough of them to make me want to do a little remodeling. So here is where I at right now. HD 28185-B has a new face and it is beautiful if I do say so myself. Much more detailed and colorful than the old one. Just have look see, you didn't think I was going to make a post without some kind of picture did you.


The Old HD 28185-B texture and old volcanic moon.


The New HD28185-B texture and new volcanic moon.

While both textures are based on modified Jupiter texture data I felt the old one was just a little drab and everything we are finding out about these extra-solar gas-giants leads to them being very dynamic places just like Jupiter. Of course this is all creative license but it does look good.
You might have noticed that I mentioned it the caption above about a new volcanic moon. Well it really isn't a new one. I just found a new home for the orphaned Orpheus texture. It should work well as a volcanic moon. I plan on tweaking it a little more to help create its own identity separate from its original origins.
Oh and one other thing. I have finally did something about a little trick I wrote about back in Feb 2003 here http://216.231.48.101/forum/viewtopic.p ... =lightning

I put a little movie together showing the effect on HD 28185. It is very subtle but it works nicely. You will need the latest DIVX codec installed to see the movie. It is about 3.35MB in size so those with bandwidth limitations might want to think twice. It plays well in full screen mode.


Well that wraps it for now. More info to follow as it becomes ready.

I was wondering when you were due for some fictional planet building...

Just as soon as I figure out lighting in Celestia you might want to have a go at 2010 again? I have better emissives so far but its rather tricky in getting them to be a light source...well since I have no clue so far why when full rendering features enabled overrides GL_LIGHT0...It seems there is another lighting approach Im overlooking...

In any event...

All looks good Don...

btw in your travels on the net make sure you try out Xenofex2 by Alien Skin...It has a far superior cloud method than flaming pears for alien clouds...With a bit of tweaking you can render nice jovan clouds aswell...

[Dollan]

Beautiful! You manage to do wonders with these textures, Don. I'm still downloading your avi file (pity my dial up connection), but I can't wait to see it.

I really need to start playing with my photo programs, and get some textures done!

...John...

Well boredom has its rewards...

[Don. Edwards]

Well it’s started snowing again.
So I am back to work on textures. I decided to upload a few more pictures of what I have done so far with more of the planets for the HD28185 system. Instead of filling this thread full of thumbnails and pictures I posted them over in my gallery. So to see the new shots go to http://www.celestiaproject.net/gallery/view_al ... me=album03
and you can see some of he new textures in action. I am not to sure about using the textures you see in the pictures of a few of them because they ended up looking a little to much like our own solar system. Basically HD28185-C looks just a little to much like Saturn, HD28185-D always looked a little like Uranus but now it is really looking like it, and HD28185-E is looking too much like Neptune. I really didn't even relise I was taking them in this direction until I plugged them in to Celestia to have a look. Don't get me wrong the textures are very nice but again they do look a little like familiar territory.
As I change things I will keep updating the gallery and dropping notices about the changes in this thread. Have fun viewing the pictures.

[Evil Dr Ganymede]

Nice. The movies rather gorgeous too, though I would have preferred if it panned away from the planet while keeping it in the field of view...

The volcanic moon looks a bit 'wrong' to me from a distance... I can still see the molten lava on its dayside in the picture you posted here. Looking at the gallery, it looks much nicer up close, but I think you might have gone a little overboard with the lava . Even Io doesn't have huge areas that glow bright red like that, visible in the day and night-time.

If you're more interested in making pretty planets then fair enough, you've done good . If you want it a little more realistic though, I'd suggest whittling down those red glowy areas somewhat. I suspect that a moon suffering that much tidal heating and stress would practically be pulling itself to pieces - which might be what you intented, maybe?

[Don. Edwards]

Hey Evil Dr.
Thanks for the kind words. I had mentioned in the first post that the moon in question was originally supposed to be a representation of the planet Orpheus that is theorized to have collided with the Earth several billion years ago and formed the Moon as a result. So it was representing a very young planet with allot of broken crust. But that project kind of fell through due to a hardware failure and NASA canceling the Celestia educational project. I thought I had lost this texture and quite a few others when a hard drive of mine failed. But as I was pulling all my Celestia data and textures together from other hard drives I found backup copies I didn't know I had.
Again as I stated above I do plan on reworking the texture some and toning down some of the lava to a lower level and brightness. The texture was made for educational purposes so it needed to have a little bit of that ooh-ah factor to it. It is also very crater covered in regions with crater lakes which I plan to remove most of them to get it more like and Io type moon. But this moon is bigger than Io so it will of course have to be very different as well. It is basically going to look like it is covered entirely of basaltic lava flows and volcanoes with a few areas of wild coloring to give it that certain Io parallel.
I am putting it at nearly Mars size as most of the moons around my version HD28185-B are larger than Jupiter’s moons by several factors. I chose to go in this direction because HD28185 is five times Jupiter’s mass so there was a great deal more material to build moons with. At least that’s my theory I guess. The volcanic moon Alpha is nearly Mars size, Beta moon will be larger and Delta will be just under Earth size. The farther out you go from there the moons will start to decrease in size. Originally I had only ten moons around HD28185-B but I am going to increase this I think to twelve. This isn’t counting the Shepard moons in and near the ring. I might through in a few odd-ball moons in weird orbits like what we see around Jupiter. I have a feeling I am going to have to get someone to look over my .ssc file to make sure I am keeping as close as possible to the Kepleran laws though. I want to keep this thing as realistic as possible. It might be a semi-fantasy system but I want it to be the most accurate portrayal of what it might really be like out there. So of course I want it to have a little bit of a sci-fi/sci-fact look and feel.
You might be one to ask about this. In my original mock-up of this system I have a mercury like planet first out from HD28185. Than instead of another planet I put an asteroid belt. My thinking was that if Jupiter kept a planet from forming in our own system think what a planet five times its mass would do. For that matter I might have to remove the first planet as well? Out from HD28185-B the giant I put a small frozen terrestrial with a large moon, and then back to the gas giants and there moons. If you would like to play with the physics of the system I could upload the old original HD28185 add-on and you could have a look at where I am going with this. I am still using most of the original settings so it would be very close to what I am working with physically at least. Or anyone reading this for that matter. Just ask and I can make it available as I don’t think it is any longer. I believe it disappeared when Bruckner’s site went down.
Well I think that covers everything.

[Dollan]

I wouldn't mind downloading it at all. Of course, I'll have to wait until next week, when I again have access to a T1 line, rather than my current dial up account.

[Don. Edwards]

Dollan,
It would be a very limited version with none of the new textures. Actually to cut down the size I was considering grayscaling all the textures as this would be for just a test of my Kepleran physics to see if it is accurate enough. I am very protective about my textures until they are ready for public use as I change then so much. I don't want a beta texture floating around in place of an updated one. I think you can see my point in this.
Most of my data was taken from our own solar system so it has to be partly following the Kepleran laws. I have sped it up way into the future and haven’t found any moons going off into space or crashing into there parent planet as of yet. But I guess if I ran it far enough this might happen. That is why I want someone with a good knowledge of the Kepleran orbital laws to have a look at the .ssc and see if I am in fact in the right direction. If no one steps up to test it for me than I will just continue working with it the way it is and if planets collide somewhere in the future or they spin off into space than I can say I told you it was untested.

And oh yah Evil Dr.
All I did when I shot the movie was hit the escape key so it would pan out. I kept trying to get it to pan straight out but I just went ahead and kept this movie as it ended up being the best.

I guess no one even noticed the lightning effect in the movie. That is what I was trying o show off with it. I guess I will have to shoot another one. Oh well it won't be the first time I made something and no one cared or noticed. I am not speaking strictly of this forum of course.

It is basically going to look like it is covered entirely of basaltic lava flows and volcanoes with a few areas of wild coloring to give it that certain Io parallel.

Well, remember that if it's bigger then the craters on it are going to look smaller. Some of the lakes there looked like they were hundreds of km across .

It might be a semi-fantasy system but I want it to be the most accurate portrayal of what it might really be like out there. So of course I want it to have a little bit of a sci-fi/sci-fact look and feel.

Well, that description of its satellite system sounded reasonable to me.

You might be one to ask about this. In my original mock-up of this system I have a mercury like planet first out from HD28185. Than instead of another planet I put an asteroid belt. My thinking was that if Jupiter kept a planet from forming in our own system think what a planet five times its mass would do. For that matter I might have to remove the first planet as well?

There'd probably be a bigger 'disrupted ring' around the jovian's orbit, yeah. I don't know where all your planets are in the system though - can you list the orbital distances of the worlds (and the star type/size)?


Oh yeah, I did spot the lightning. I've not seen a movie of Jupiter's lightning on the global scale though. I'd imagine there are lots of lightning bolts flashing around the atmosphere all the time though, so if that's the case then yours looks realistic. Judging by this picture from Galileo and extrapolating from that it would seem that's on the right track though.

I named the planets in order of what would be the order of there discovery. HD28185-B being the first and then C, D, and so on. The gap between G and B is the location of the asteroid belt. The orbits of the asteroids vary and I do not want to take up allot of space plugging in all those positions into the master .ssc. So they exist in a separate add-on .ssc file. That way they can be used or not. Most of them are centered on what would be the orbit of a planet if it did exist. Also you will see I plugged in a terrestrial planet after HD28185-B. I am not sure if the tidal disruptions of HD 28185-B could also keep a planet from forming here. But I am thinking of changing this to a small gas giant instead. So have a look and see what you think. Since the whole thing is for the most part based on our solar system there should be some Kepleran law in place. You may find a discrepancy in the orbits of HD 28185-B's moons as they were setup before I discovered that almost all super gas-giants will be Jupiter size even if they are 5 times more massive so I had to resize the planet back to a more expected size, I had its Radius set to 111574, and this means of course all the moons orbits need to be moved inward slightly except for the Shepard moons. So give all the info a going over and see what you think and please by all means point out anything that is out of place and if you have any ideas please send them my way.

Of course anyone can copy this info into a text document and save it as a .ssc and then drop it into your extras folder and visit a bunch of white orbs orbiting HD 28185. A very few of the moons will be skinned by your default Phobos, Deimos, and Asteroid textures.

Hi !

Is your addon ready ? Where can we download it ?

[Cham]

I tried your info in Celestia. It's working well, except that all planets are white orbs. Thanks a lot for the ssc file. How can I add high resolution textures ?

[Don. Edwards]

Hey Everyone,
Now that I have figured out what happened to the forum, I missed Chris' message before the change-over, I have some new HD28185 add-on shots to share. What you will be seeing are pretty much the finished textures for the inner moons as they stand now. Of course there is always room for some improvement and if you see something that looks odd do not hesitate to comment on it. So here we go.

The totaly new Volcanic or Alpha moon texture!

And here is something I don't normaly do. A view of HD28185B from the Surface of Alpha moon.



New texture for Beta moon.

And another surface shot from the surface of Beta moon.

Beautiful work Don! The vulcan class moon is a far improvement of its predecessor.

[Cham]

Is it ready to download ?

[ajtribick]

Looks great...

As a (developing) 3D artist I'd just like to know how you go about creating those textures.

[Psykotik]

Don, any news ?

[Don. Edwards]

Psykotik,
If news you mean a posible ETA of release, no. My time isn't what it used to be. I only really get to work on any of my projects on my days off. I am just exusted from work to turn the computer on when I get home. So it is going to be slow going. Thats why as things move along I will be posting images in this thread to document the progress. Remember I am not working with just one texture but over twenty textures. I want them to be as unique as posible. So this takes time.
Here is a shot of the worlds done so far and the one I am working on now. It is in the forground.



BTW,
The above image makes a nice desktop pic.

[Psykotik]

I don't mean to be exigent. I really enjoyed your first volcanic moon (I'm still playing with !), and I'm some enthusiastic about your new work.

Take your time, everyone knows the work that represents a full solar system

BTW, thanks for the screenshot. The earth-like seems to be very detailled !

[Rassilon]

...My time isn't what it used to be. I only really get to work on any of my projects on my days off. I am just exusted from work to turn the computer on when I get home...

Glad im not the only one...I was beginning to think I was being lazy
